In this period in 221 observation nights, 5544 CCD images were obtained, which covered 648 square degrees of sky. Of them, about 1000 CCD images were devoted to studying the dynamics of NEO-type and Main belt asteroids. For asteroids, rotation periods and amplitude of brightness variation in the G(RP) passband were obtained. Photometric data reductions for the CCD images were done using the MaxIM DL program. The G(RP) photometric magnitudes for reference stars were taken from the Gaia DR2 release. Through 15 minutes and 5 minutes steps using second-order Fourier analysis, the best size of periods for eleven NEO and main belt asteroids was determined.\u0000\u0000 Our main goals are contributing to checking our methodology to obtain the rotation periods by analyzing photometric broadband measurements.","PeriodicalId":52135,"journal":{"name":"Astronomical and Astrophysical Transactions","volume":"66 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-02-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84746782","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

That is necessary because of two reasons 1) data are in digital form and 2) data processing is a complex multi-step process. In this paper created in VIRAC data processing suite for a single radio telescope, space maser observations are presented. Software Defined Radio (SDR) backend data processing is described. Implementation of the frequency switching algorithm, acquisition of observation data and their format for storing are discussed. Multiple ways to display the observation results are highlighted.","PeriodicalId":52135,"journal":{"name":"Astronomical and Astrophysical Transactions","volume":"22 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74451768","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
